ELECTRICALLY-HEATED KITCHEN-RANGE.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed November 4, 1914. Serial No. 870,225.

To all whom it may concern Be it known that we, OSKAR SJELII) andKRISTIAN. PETTERSEN, subjects of the King of Norway, residing atSarpsborg, Norway, have'invented certain new and useful Improvements inElectrically-Heated Kitchen- Ranges; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

Ourinvention relates to electrically heated kitchen-ranges with heataccumulating medium.

The main object of the invention is to provide a kitchen range of thiskind, which will be adapted for cooking as well as for frying'purposeswith heat from top as well as from below.

The invention consists in the provision of means for regulating the heatto the several cooking vessels, whereby a range is provided that is wellsuited for the several varying household purposes.

()n the drawings, Figure 1 is a vertical sectional view through therange. Fig, 2 is a detail sectional view. Fig. 3 is a plan of aninsulating belt for the cooking vessels.

The range consists of an insulated tank 1 filled with wate' and providedon the top with suitable openings or recesses for blocks 2, 3, l, heatedby electrical resistance elements 5, G, 7 and supported in receptaclesadapted to form cooking or frying chambers inside said tank. In the topplate of the range there is also provided openings for one or morevessels, which form heating chambers serving to complete the cooking offood the initial cooking or frying of which has taken place on theheating blocks. On the drawing there is shown three heating blocks andone heating chamber, but any convenient number of these parts may ofcourse be provided.

The heating bloc 2 serves to heat-one or more cooking vessels, placed onthe top of same and also to heat the water in tank 1. The insulatinghood on top of said block may consist as shown of several parts 8, 9

in place by friction so that their position may be adjusted according tocircumstances. Thus the blocks may be placed at a certain distance fromeach other, the space between them then being suitable as a fryingchamher by utilizing the heat stored in both blocks. On the top of block3 is provided a thick iron plate 13 which may be moved independently bymeans of rod 11 so that another frying chamber may be provided on thetop of block For regulating the transmissionof heat from block 3 to acooking vessel thereon a' cover 15 of asbestos or the like may be placedbetween them.

The blocks 3 and 4 may be removed from their chamber and be placed in aseparate insulating vessel for cooking outside the range. The block 1provided with the h at ing element 7 is mounted in a heat insulatinghood is placed in a tight vessel 19. which projects downwardly into thewater tank 1. Above the block 4 room is left for a cooking chamber 20.Beside this cooking chamber there is placed in tank 1 another vessel 21forming a heating chamber for n'eheating and l'reeping hot the food. Thevessel '21 is closed at the bottom by means of a floating plate 22provided with a water-tight packing 24 and operating as an automaticvalve to prevent escape of steam. By using the floating plate as shownon the drawing, one may take hot water up through the chamber 21 bypushing down the plate 22. The lat ter is made of a material lighterthan water or.it may be. a hollow metal body which will operate the sameas the well known form of float valve. The chamber 21 may also in asimilar way be utilized for cleansing the tank. Above the plate 22 isplaced a grate having feet 27 resting on an inwardly projecting flangeon the inside of the cylinder. The grate 23 serves to support a cookingvessel (not shown), which may be placed in heating chamber 21.

The insulating cover 25 for the-chamber is provided on its undersidewith a cooking plate 26, which may be heated electrically. Theinsulating cover is connected by a hinge 28 to the top plate 38, so thatit may be turned on its hinge to cover chamber 21 (Fig. 2) or thecooklng chamber 20, as shown on Fig. 1. The hinge 28 may also be mountedto swing on a vertical trunnion, so that the cover 25 may be placed inany convenient position on the range. The insulating cover 25 and thecover 29 may be used alternativeb The efliciency of the heating may beincreased by means of an insulating ring 30 (Fig. 2). placed around theedge of the insulating cover. The efficiency may be further increased bymeans of a belt 31 (Figs. 2 and 3) consisting of sections connected toaring, which is placed around the cooking vessel on ring 30 for thepurpose of covering the space between the cooking vessel and the ring 30when vessels of different sizes are used.

A ring 32having two rods 33 connected by bail 39 serves for handling thecooking vessel in the cooking chamber 20. The ring 32 is adapted toreceive what is spilt from the cooking vessel, so that the heating blockis not polluted. The ring 32 is provided with suitable nubs 34 by meansof which the cooking vessel may be kept at a certain distance from thehot surface of the heating block by I lifting the ring with the cookingvessel and turning it partly. The nubs then slide along the slopingparts of teeth 36 arranged below said ring. The regulating of the heattransmission to the cooking vessel may thus be effected by means of thering 32.

The cover 25 and its cooking plate 26 may be. used separately. By meansof the insulating ring 30, there may also be provided a frying chamberby using two insulating covers with their cooking plates or oneinsulating cover and a heating block.

As shown on Fig. 1 the tank is preferably formed of two parts, the upperpart being the plate 38 containing the several cooking arrangements.

The tank 1 may be provided with inlet pipe 37, which may be connected tothe main, but which may also be utilized for letting out steam to asuitable heat chamber (for heating plates). The water supply may be madeto operate automatically by using a bent tube 40 connected to a waterconduit.

\Ve claim:
